Who is Hiro Emiko? Saiki Kusuo x OC

[UNDER HEAVY EDITING/REWRITING]
Saiki Kusuo disliked new students because they all ended up as tragically strange people. God, who loved sending people to bother him sent him someone who he couldn't resist in becoming friends with, but there was something about her that made him sure she wasn't normal.

Slow burn.
Long chapters ahead. :))

UPDATE: I wrote this long ago and I realise there are so many things I wish I could change-maybe I still can, but for those of you who have been reading this a while back, I hope you still enjoy whatever big or little changes I added. Although honestly I can't change that much because young me had already laid the ground work. Hehe
